PEDAL ATTACHMENT FOR ORGANS.

SPECIFICATION forming part of Letters Patent No. 447,560, dated March 3, 1891.

Application fil October 9 1890. Serial No. 367,519. (No model.)

To all whom it may concern.-

Be it known that I, MILTON B. CROWELL. a citizen of the United States, and aresident of Newport News, TVarwick county, Virginia, have invented certain Improvements in Pedal Attachments for Organs, of which the following is a specification.

My invention consists of certa n improvements in that class of pedal attachments which are carried by the players stool and can be folded up under the stool when not in use, the objects of my invention being to construct such a pedal attachment for application to an organ, to provide for the operation of the bellows of the main organ by means of a handlever carried by the stool, to insure the firm anchoring of the stool and its pedal attachment to the main organ, and to provide for the disposal of all of the parts within the limits of the stool when the attachment is not in use. These objects I attain in the manner hereinafter set forth, reference being had to the ac companying drawings, in which Figure 1 is a transverse section of an organstool with pedal attachment in accordance with my invention, the pedal attachment being shown as adjusted in position for use. Fig. 2 is a similar section showing the attaohment folded as when not in use. Fig. 3 is a rear view of the stool. Fig. is a plan view of the stool and its attachment, the latter being in the position shown in Fig. 1 and Fig. 5 is a sectional viewillustrating a modification of the invention.

A represents the top, and A the opposite end supports, of an ordinary players stool for use with an organ. Extending from one of the supports A of the stool to the other near the front of the stool and adjacent to the floor is a rod to, to which is hung a frame 13, this frame being rectangular in the present instance and being secured to the rod to by one or more turn-buckles b, so that it can be readily removed when such removal is desired, or can be swung on the rod either to' a horizontal position, so as to rest on the floor and project in front of the stool, as shown in Fig. 1, or to a vertical position, so as to be turned up within the limits of the stool, as shown in Fig. 2. This frame carries a series of pedals D, each of which is adapted to actuate a valve in a reed-box F, also carried by the frame, said reed-box receiving its air-supply from the wind-chest of the main organ X through the medium of a flexible pipe or tube as, as shown by dotted lines in Fig. 1.

To bearings on the front of the frame B are adapted rock-shafts (1, each of which has two armsfand g, the arms f bearing upon the foot-boards y of the bellows-actuating mechanism of the main organ. To the arm g of each rock-shaft is connected a cord or wire h, which passes round guide-pulleys 1) on the frame B and on the cross-bar G of the stool, one of these cords or wires h being connected to one arm and the other to the opposite arm of a lever J, which is hung to an arm m, pivoted to the cross-barll of the stool, the upper end of this arm on swinginginto a socket a on said cross-bar H, and being retained in position therein by a pin 17, Fig. 3.

TheleverJ projects beyond the end support A of the stool, and has a suitable handle by which it may be manipulated, said lever thus serving as a means for operating the bellows of the main organ, and thus providing asupply of air for the latter and also for the reed-box of the pedal attachment.

In order that the stool and its attachmentmay be rigidly anchored in their proper position in front of the organ when the attachment is in use, the frame B has at each end projecting tongues or fingers s, which are inserted beneath the frame of the organ, and thus serve to retain the frame B and the parts carried thereby close to the floor and prevent any displacement, either of the frame or stool, such as might otherwise be caused by the movement of the player.

Vhen it is not desired to use the pedal attachment, the stool is withdrawn until the tongues s are pulled from beneath the frame of the organ,-whereupon 011 detaching the tube 00 the pedal attachment is free to be turned up under the stool, as shown in Fig. 2. Upon withdrawing the pin 19 from the socketplate 71 the arm or and the pumping-lever J, carried thereby, can be thrown down to the position shown by dotted lines in Fig. 3, so that said lever will not project beyond the end frame or support of the stool.

Although I prefer to use in carrying out my invention the rock-shafts d, having arms f and g, simple bell-crank levers may be substituted therefor, if desired, the cords h in this case running backward at an angle, so as to give the desired spread when the cords are carried up to the lever J, and a single rock shaft or bell-crank lever might in some cases be used instead of the duplex arrangement shown, although the latter is preferred, as most organs have a duplex foot-board for operating the bellows mechanism.

Although in carrying-out myinvention the reed-box is preferably located beneath the pedals, so as to renderthe attachment as compact as possible, this construction need not necessarily be adhered to in all cases. For instance, in Fig. 5 I have shown a reed-box F located in the rear of the frame B, the pedals D in this case'being in the'foimof bell-crank levers, so that they may properly act upon the valve-stems projecting from said reed-box. j

Having thus described my invention, I claim and desire to secure by Letters Patent 1. The combination, in a pedal attachment for organs, of the stool, a pedal attachment carried by said stool and projecting in front of the same, a pumping-lever hung to the stool, and means whereby the movementof said lever can be transmitted to the bellows mechanism of the main organ, substantially as specified.

2. The combination, in a pedal attachment for organs, of the stool, a pedal attachment carried by said stool and projecting in front of the same, a pumping-lever hung to the stool, means whereby the movement of said lever is transmitted to the bellows mechanism of the main organ, and a pipe or conduit afiording a communication between the win dchest of the main organ and the reed-box of the pedal attachment, substantially as specified.

3. The combination of the stool, the pedal attachment having a frame connected to the stool, lever mechanism carried by said frame for acting on the foot-boards of the main organ, a pumping-lever hung to the stool, and cords or like connections between said pumping-lever and said foot-board levers, substantially as specified.

4. The combination of the stool with a frame connected thereto and projecting beyond the same, pedals mounted in said frame, and a reed-box located beneath said pedals, substantially as specified.

5. The combination of the stool, a frame pivoted thereto and carrying a reed-box and pedals, a pumping-lever hung to the stool, and means for transmittingthe movement of said pumping-lever to the foot-boards of the main organ, substantially as specified.

6. The combination of the stool, the pedal attachment carried by said stool and projecting in front of the same, and tongues or fingers projecting from said pedal attachment, so as tobe inserted beneath the frame of the main organ, and thus serve as anchors for said pedal attachment, substantially as specified. I

7. The combination of the stool, the pedal attachment carried thereby, thepumping-lever carried by an arm hung to the stool, and

a detachable retaining device for said arm, whereby the arm and its lever may be moved MILTON OROWELL.
